Solution

The correct option is B A heteropolymer
Peptidoglycan is a structural heteropolysaccharide made up of repeating units of N-acetylglucosamine and N-acetyl muramic acid.

Cellulose is a structural homopolymer made of glucose units. A homopolymer is a polysaccharide made of only one type of monomer units.

Oligosaccharides are carbohydrates with 3-10 monosaccharide units.
An example is a stachyose which has 4 monosaccharide units - one glucose, two galactose and one fructose unit.

A homopolymer is a polymer made up of only one type of monomer.

A heteropolymer is a polymer made up of more than one type of monomeric units.
